ing the flush gate! valve the dripvalve or t valves v'will unctiontoclose,

Another` object ofthisinvention is to provide a milk drip which willfunction to operv ate in Vconjunction with the main valve, it being.understood that the main valve functions a to closeoff the supply omilk`from the pas;

teurizer, but it, has been found from experience that a leakage, occursduring thefperiod Yof pasteurization, and this leakage or'rdripi'ordin'a'rily flows into the pasteurized product,

- which is objectionable'for many reasons, and

the drip valve, according to this invention,

j provides an efcient, means for eliminating vthe leakage problem. v-

'Another objecto'i thisinvention is'to provide a flush gateyvalve'having a plurality of valve members mounted upon the valve stem insuch a manner'that one'of the members Will function to eliminate thepossibility of un pasteurized milk or other objectionable matter fromflowing into the sanitary pipe line.

A further object of this invention is to prolvidea main valve having astem andl means connected with the stem for opening and closing the mainvalve, and any auxiliary valve l mounted on the stem `for closing olfthe sanitary'pipe line when the main valve is closed, drip valves foreliminating leakage, and au tomatic means for opening the dripv valveswhen closing the main valve, and closing the drip valves when openingkthe Vmain valve,` and Y means mounted on the valve housing for lock-ving the valve in either open or closed position.

Another object of this invention is to provide a valve mechanism whichmay be read# ily connected to the pasteurizer Without the forming r ofgrooves or curves in the lining thereof.

` Other objects ofy this invention will appear from thefollowingdetailed description of the device, and asy disclosed inthe twosheets of drawings, which are herewith made a part of thisvapplication.l In the drawingsi n Figure l illustrates a sectional viewof the Hush gate and drip valve, disclosing the varions membersmthereofin operative relationship toeach other. a i

In order to aid in the sanitary delivery ofthe milk, the innerY flange 19 of the nipple6 is formed having anoutwardly extending shoulder portion 20 for cooperating withthe inwardlyextending flange 5 of the coupling 4, the edges of bothv the flange 19and the portion 2`of the house ing lvbeing bevelled, as at 21, for thepurpose of positive alignment when the nipple and the housing 1 areclamped together'. v-

The flush gate valve in this invention is pre ferred to be formed havingastem 22, the

' main valve 7 being threadably'mounted there on at its inner end 23,while the valve member 8 isadapted to be slidably mounted on the outerend, as clearly disclosed in Figure 1, the

outer end of the stem 22 .extending a suitable distance beyondthe valve8 in orderto loosely receive thereon 'a tensionspring member 24 for thepurposeof resiliently holding'the s valve -member 8 Vin the seatrportion25 and against the collarsection 26, which may Vbe housing 1, thelopening 32 beingoi''smallerV periphery of the pipe k'memberll.v Y Y 37are formed either integrally with the stemf cooperating with a similarsurface on the valve seat portion 31, which extends inwardly in the formof a-iiange at the inner end of the diameter than the inner Y Atpredetermined positions along the stem 22, lug or collar portions 26,33, 34,35, 36, and

In' order toehminate-the leakage or drip problemwhich'occurs in case offlush gate valves connected with pasteurizing appara-j "eok tus,thisinvention provides a'drip valve 50 operablyarranged in connectionwith the hous-A ing 1 and the valve stemf22. vEither arsingle drip`valve or a rplurality ofV drip valves .5()A may be usedwithout aectingvkthe'jspirit'of this invention."

4The'drip valve comprises a mainbody portion 50 of spherical formation,made of any suitable material, suchas cast steelfor the like, i

portion 52 extends from thernain section 56' and is provided at itsinner end with a forked `portion 53 adapted to embrace the stem 22 be-Vtween thecollar sections 34, 35, 36 and 37. i The stem 52 ofthe'drip*valve 50 extends V through an opening 54, being-bounded by an upwardlylextending lia-nge 55having1a threaded` portion 56 vforcooperatin'g witha coupling member 5.7,"thefspherically shaped yand providedwithranopening 51. A. stem f im Y valve portion 50 being movably'moiinte'dand iheld firmly in operative position between' the flangeportions 55'and thecoupling 57 when *v they are brought together under tension. i Thecoupling- 57 :is'furthermoref provided with p f threaded sectionV 58 forthe purposeof receiving a pipe linerinto which the leakage or drip maybedelivered.' i ff The valves 50V are so arranged in relation- Y `shipto the movement of the valve members 7 Vand 8 that whenthecontrol lever38 is` moved in one direction for opening the .valves 7 and 8, the drip`valves and openingsV 51V will close, andthe ,actionV in' the oppositedirection will be exactly ftheL reverse. Y In operation this inventionprovides .ai flush gate valve in combination with a sterilizing system.vThe valve portions within inverses the main housing are so arranged thatthe danger of contaminating the sanitary pipe line is practicallyeliminated, there vbeing a `valves are located in connection with the vhousing between the two valve port-ions therein, in such a manner thatthe leakage or drip remaining in the housing after the valvesr Vareclosed will be 'eciently discharged.

. Also, this invention provides a very eili-y ycient locking device .forconveniently7 holding the valves in closed or openposition, as

n may bedesired.
